Jaws 3 (1983)

Everyone at Florida's Sea World is thrilled with the new “Undersea Kingdom,” a maze of underwater plexiglass tunnels that permits visitors to get closer to marine life than ever before. The opening ceremonies include many important guests… and one uninvited baby shark who accidentally enters the park's lagoon through a faulty sea gate and subsequently dies. The young shark's 35-foot mother soon follows her offspring, creating the most horrifying tale of terror ever filmed in the water. Directed by Joe Alves, the original Jaws designer, co-written by Carl Gottlieb who penned the first two blockbusters, and starring Dennis Quaid, Bess Armstrong, and Louis Gossett Jr., this action-packed adventure will have you screaming for your life.
